Sounds like your compressor is seized or a start fault. If the unit is under five years old it should be under warranty. Call Fujitsu warranty out to have a look at it for you.
Contact details as follows

Sorry but either way I think your going to need a part there is very little that I can do unless your in WA.

Hope this helps

4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
and signal will be transmit to the main unit.
5 Each press of the button (? or ?) will increase error code
number and transmit error code signal to the main unit.
6 When the latest abnormality code on the main unit and
code transmitted from the remote control are matched,
Power LED will light up for 30 seconds and a "beep" sound
(continuously for 4 seconds) will be heard. If no codes are
matched, Power LED will light up for 0.5 seconds and no
sound will be heard.

The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until "beep" sound heard following by pressing the "CHECK" button at remote controller.
Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error Codes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound is changed from one "beep" to four "beep" sounds.

A/C Unit SAMSUNG -Outdoor unit model= MH080FXCA 4A was connected to 3 indoor units:


It's possible you have a bad data wire on one of the systems. Swap the data wire or both if two with a different wire. (1&4--2&3) whatever. Whatever you do inside obviously do outside. Might have extra resistamce that is throwing the error but will be fine for a ground wire.Or do one system at a time, being sure to change your dip switch settings until you figure out the problem unit. Good Luck!!

When we put on the air conditioner it shows F1 or ERROR on the window. What is the problem?


Hi Charity, F1 is a communication fault, I hope this helps......... CHEERS..
1?Check whether the connection of the outdoor unit and indoor unit is one to one, otherwise connect the L, N and communication line of the indoor unit and outdoor unit one to one.
2?Measure whether the voltage between the zero line and the communication line is 18V-30AC half-wave signal, check whether the communication circuit on the indoor and outdoor electric control board has been damaged, otherwise replace it.
3?Check whether the LED on the outdoor power board has been on, otherwise replace the electric control board.
4?Check whether the unit is abnormal caused by the external interference, if it is, then find the interfering source, and removes it.

Sounds like an interconnecting wiring error. Check wiring connection i.e. wires are connected in right order 1 to1 2 to 2 etc. from indoor terminal board to outdoor terminal board. Also check for slack or loose connections.

I have had this problem with a Fujitsu unit before. If the power is supplied to the outdoor unit first but unit is meant to have power supplied to indoor unit first, outdoor will only stop when power is cut off! In that case, you will have to run the power cable to the indoor unit first and then connect from appropriate terminal back to outdoor unit. (Often the indoor will stop outdoor unit by just cutting the power to it via use of a relay on the pcb.)
